The new iP PD1-4 from Juice Goose has four 20-amp circuits for a total current capacity of 80 amps and each circuit is individually addressable via a browser connection to an on board web server. Remote access is also possible via RS232, UDP or TCP using text commands over Ethernet. Current load can be monitored for each of the four circuits.
The four foot wire harness includes a separate hot and neutral leg for each circuit plus a shared common ground line. The side mounting brackets have long openings. Mounting flexibility is increased further as the brackets can be relocated in various positions up and down the back of the chassis. The iP PD1-4 lists for $861. Here is more information.
